Okay so I got a little impatient and went ahead and installed Ubuntu using Parallels.

I was looking for a perfect emulation of the OS and I don't think that's what I got. Everything seemed cloudy and of very low quality. Or maybe I'm just too used to my Mac.

Not only that but I can notice a few minor performance changes when running Mac OSX. Mostly a slightly longer startup time. Nothing major but having it happen on my 1 week old once perfect macbook kinda bothers me.

Speaking of this, does Parallels reserve ram even though the virtual machine isnt running? This is what the memory column reads in iStat Pro.

Memory:
Wired: 198 MB
Active: 141 MB
Inactive 622 MB
Free: 1.06 MB

This is out of 2GB ram total. Is that normal? I never really paid attention to it prior to installing parallels but having only 1.06 MB left while only running firefox doesn't seem right.

So I guess the questions I have now are:

1) Does Parallels drain memory even when not in use?
2) How do I completely undo everything I did to install Ubuntu?
